  There were a number of bugs the very early revs of the VMD
mmCIF/PDBx plugin that have subsequently been fixed that may
explain the crash you have encountered. Thanks for reporting
this. I'll see about adding this as a test case with the current
version and make sure this is fixed in the current rev.
